Chemistry is traditionally divided into organic and inorganic chemistry. Recommanded Product: 52409-22-0, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent£¬Which mentioned a new discovery about 52409-22-0
Diastereoselective synthesis of 2-vinylpyrrolidines and 2-vinylpiperidines by the palladium-catalysed cyclization of amino-allylic carbonates containing a chiral protecting group
An efficient diastereoselective synthesis of pyrrolidine-and piperidine-type N-heterocycles is reported, by the intramolecular Pd(0)-catalysed cyclization of amino carbonates containing chiral protecting group. The use of chiral auxiliary in the cyclization gave the corresponding heterocyclic derivatives in excellent yields and with good dr values.
